On a stock 5870 at AGRESSION=12, I get 371 (vs. 353 with the default kernel) and O/C at 1GHz i get 438 (vs. 420 with the default kernel)
With VECTORS and BFI_INT it compiles to 1418 ALU ops for 2 hashes.

Id you're feeling generous, any donations would be greatly appreciated so I can continue to put out bitcoin related software:

On 5870 900/300 383.17 -> 398.16
On the 5850s 852/284 327.12 -> 340.90

CLI:
DISPLAY=:0.0 python phoenix.py -q 2 -u http://15xWuDHSyKzpvp6FacGKXijBeaaaYhKWSi:x@pool.bitcoin.dashjr.org:8337/ -k phatk DEVICE=$1 AGGRESSION=13 WORKSIZE=256 VECTORS BFI_INT

SDK 2.4

While screwing around with memory settings previously I found that having an integer ratio of clock to mem made a fair improvement, around 3MH/s with the old kernel vs being near but not quite. I wasn't sure if this was chance or something substantive, but considering that I'm seeing better improvements (and performance) than some others I thought I'd mention it.

Phateus, you have my thanks and a donation of a day worth of the income improvement your code brought me.

not for me, 1020/344 has about 5Mh/s advantage over 1020/340 and another 5Mh/s than 1020/510
